Mike... the circuit I have for the router and dust collector is a 20 amp 120v. So, the 240D25 SSR you recomment whould be more than double the rating I need, right? (240V 25 amp would be 120v 50 amp capacity?). I happen to have a GE contactor, 30 amp, 3 pole with a 110-120v coil. I should be able to drive that with the SSR and just use one pole to break the hot side of the my power line. Sound like I'm up to speed here?
The shielded cable you metion for the low voltage side... is this like coax cable?
Thanks,
Lynn

I know this is an older thread but i got interested in it while thinki8ng about a way to automatically turn off my dust collection when the router turns off after the file is done. Sometimes I do lithopanes that mean the machine is running 4-5 hours and I have a camera setup so i can keep an eye on the bot working while i'm watching football. Now the shopbot tech guys could answer this, but i'm wondering since I have my router power supply run into the shopbot control box that turns the router on/off why couldn't you run a power line from the same terminals to a receptacle box, plug your dust collection into that and it will then turn on/off same as the router? Is there same voltage constraints or surge issues that would cause a problem?

I wouldn't use the contactors in the box to turn anything but the router on/off. They are rated to run a single router and nothing more.
If you want to turn the DC or any other accessory on/off, use a relay board in conjunction with your accessory. Output switches on the board can be used to toggle the accessory on & off from the software. There should be a few references to making a relay board for this purpose if you use the search function.

Relays board/box; I believe SB has one or you can build up your own. The schematic is somewhere in the documentation but here what I have about the Alpha (24V) system.

I'm in the process of building mine but it won't be switching until a few days or weeks... more later...
